First you find the median which is 4. The mean is calculated by the sum of the distribution divided by the amount of numbers in the distribution (20). The mean comes out to be 4.35. Subtract 4.35 from 4 and your answer is .35.
The slope is 4/2, simplify to 2/1 or 2.
-3 x + 1 > y
1/2x -1 (less than or equal to) y
